Pressure Relief Valve DBW30B2N5X/100US6EG24N9K4R12 - Bosch Rexroth R901216231

The DBW30B2N5X/100US6EG24N9K4R12 keeps pressure in a low pressure stage between 2 and 100 bar while the circuit itself stays rated for a maximum operating pressure of 350 bar. Flow capacity reaches 650 l/min.

Benefits

• The narrow 2 ... 100 bar range gives finer resolution of the pressure setting than a spring covering the whole pressure band.
• Flow capacity of 650 l/min in size 32, so it also suits rapid traverse circuits moving large oil volumes at low pressure.
• Seat valve design with low leakage in the closed state.
• Maximum operating pressure of 350 bar at a weight of 7 kg.
• Subplate mounting with 2 ports to ISO 6264-10-17.
• Electrical unloading at 24 VDC through a connector, 3-pole (2 + PE) to EN 175301-803.

Application

A typical use is in rapid traverse and prefill circuits of presses, where a lot of oil moves at low pressure. Cooling and flushing circuits with large recirculation can also be protected with it. Solenoid unloading switches the branch pressureless for changeover steps.
